I'm working my way through enabling and configuring IPv6 on OpenWRT. I've been very pleased at how much has Just Worked so far.
I would like the host identifier of the link-local address on the LAN to be ::1, like the ULA and global unicast addresses are:
5: br-lan: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP qlen 1000 link/ether 00:24:a5:xx:xx:xx brd ff:ff:ff:ff:ff:ff inet 192.168.10.254/24 brd 192.168.10.255 scope global br-lan valid_lft forever preferred_lft forever inet6 2607:xxxx:xxxx:xx00::1/60 scope global dynamic valid_lft 475034sec preferred_lft 475034sec inet6 fde2:xxxx:xxxx::1/60 scope global valid_lft forever preferred_lft forever inet6 fe80::224:a5ff:fed8:5882/64 scope link valid_lft forever preferred_lft forever
I'd like the link local address to be fe80::1 instead of that long address it picked.
I've been reading the book "IPv6 Fundamentals" by Rick Graziani from Cisco, and it has lots of examples of routers being configured with ::1 and ::2 etc on the link-local, because that address ends up being used as the default gateway for downstream clients, and having it be a simple, easily recognized address is handy.
I can't find any information in the docs as to how to suggest a link-local address.
config globals 'globals' option ula_prefix 'fde2:xxxx:xxxx::/48' config interface 'lan' option type 'bridge' option ifname 'eth0.1' option proto 'static' option ipaddr '192.168.10.254' option netmask '255.255.255.0' option ip6assign '60' option macaddr '00:24:a5:xx:xx:xx'
I also have the option that is shown in LuCI as "IPv6 suffix" set to ::1. I'm not sure where in the config files that is so I can't show it.
I've really made very few changes to the default settings. Again, I'm very please with how well things have just worked, and how things have very sane defaults.
